I loved my Hi-Power I had back in the 80's, but the drawbacks I had with it were as follows:

The magazine release button stuck out so far that the lousy flap holsters were were forced to use at that department would tend to make contact, press the button, and pop the magazine loose. It would then extend just enough that if I had to draw and fire, if it fired at all the magazine would drop, and now I had a metal club instead of a pistol. I took to cutting out the leather to fix that, but caught flack for "modifying" my gear.

For off duty carry, my body sweat when carrying MOB would cause the screws in the grip would rust, and micro rust was forming on the blued finish.

Other than that, I loved it and regretted selling it to get a Glock. Never regretted getting a Glock, just wished I had not sold such a beautiful pistol that I could drive nails with, but being a new, poor cop made such choices necessary.....and I still wish I had it...wait a tic....., I wonder if my local hole in the wall gun store has a used one ..... (looks back and forth with an evil grin while rubbing hands together...)
